Can silkworms climb glass or plastic? More specifically the babies/hatchlings. My mom keeps telling me that they can because it happened when she was little and did them for a science fair project. She told me that they were all over her dresser. But from my experience small and large do not climb glass and I see others have them in plastic and glass as well. My set up was a 2.5quart deli style paint bucket with a big hole cut on top and in between the bucket and the lid I sandwiched a piece of cloth so that the container could breathe and the worms couldnt get out
